Embodiment 1

[0074] According to the method for forming vascular embolism in non-human animals of the present invention, a miniature pig myocardial infarction model is prepared, specifically as follows:

[0075] (1) After weighing the miniature pigs, give ketamine 10-15 mg / kg, midazolam 0.2-0.4 mg / Kg, and atropine 0.03 mg / Kg intramuscularly. After about 5-10 minutes, the miniature pig could not stand still and fainted. After cleaning, the embolized area was depilated, and the ear vein channel was established. Ketamine 8 mg / kg.h was continuously injected intravenously by a micropump.

[0076] (2) Send the minipig into the catheterization room, fix it on the V-shaped groove in the supine position, place it on the catheter bed, perform ECG monitoring, oxygen inhalation, and pulse oxygen monitoring to monitor the oxygen saturation, and take insulation measures at the same time. The bilateral femoral artery puncture area was routinely disinfected and draped, the femoral artery was percutaneou...

Abstract

The invention provides a device and system used for forming vascular embolism and application of the device and the system. The device is a 'sandwich' structure penetrated by a guidance guide wire and comprises the guidance guide wire, a first half balloon body, a second half balloon body, a sponge body and a pushing rod. The head end and the tail end are defined for the guidance guide wire; a first half balloon inner cavity is formed in the center of the first half balloon body, and the first half balloon body is arranged on the guidance guide wire in a sleeved mode through the first half balloon inner cavity; a second half balloon inner cavity is formed in the center of the second half balloon body, and the second half balloon body is arranged on the guidance guide wire in a sleeved mode through the second half balloon inner cavity; the sponge body is arranged between the first half balloon body and the second half balloon body, and the guidance guide wire penetrates through the sponge body; the pushing rod and the second half balloon body are connected into a whole. The device can effectively embolize the blood vessel and accurately control the embolism level.

Description

technical field [0001] The invention relates to the field of medical instruments. In particular, the present invention relates to devices, systems and uses thereof for forming vascular embolisms. More specifically, the present invention relates to devices, systems and uses thereof for forming vascular embolisms in non-human animals, methods for forming vascular embolisms in non-human animals, and embolized coronary artery preparations for screening pro-angiogenic Novel Drug Approaches to Large Animal Models of Myocardial Infarction. Background technique [0002] Cardiovascular disease is a major disease that threatens human life and health today, and ischemic heart disease is the focus of cardiovascular disease. According to statistics released by WHO in 2011, about 7 million people die from ischemic heart disease every year, accounting for 12.8% of all causes of death. According to the forecast of the World Health Organization experts, from now to 2030, myocardial infarc...
